Does vancomycin resistance increase mortality in Enterococcus faecium bacteraemia after orthotopic liver transplantation? A retrospective study.

BACKGROUND: The relevance of vancomycin resistance in enterococcal blood stream infections (BSI) is still controversial. Aim of this study was to outline the effect of vancomycin resistance of Enterococcus faecium on the outcome of patients with BSI after orthotopic liver transplantation (OLT). METHODS: The outcome of OLT recipients developing BSI with vancomycin-resistant (VRE) versus vancomycin-susceptible Enterococcus faecium (VSE) was compared based on data extraction from medical records. Multivariate regression analyses identified risk factors for mortality and unfavourable outcomes (defined as death or prolonged intensive care stay) after 30 and 90 days. RESULTS: Mortality was similar between VRE- (n = 39) and VSE- (n = 138) group after 30 (p = 0.44) or 90 days (p = 0.39). Comparable results occurred regarding unfavourable outcomes. Mean SOFANon-GCS score during the 7-day-period before BSI onset was the independent predictor for mortality at both timepoints (HR 1.32; CI 1.14-1.53; and HR 1.18; CI 1.08-1.28). Timely appropriate antibiotic therapy, recent ICU stay and vancomycin resistance did not affect outcome after adjusting for confounders. CONCLUSION: Vancomycin resistance did not influence outcome among patients with Enterococcus faecium bacteraemia after OLT. Only underlying severity of disease predicted poor outcome among this homogenous patient population. TRIAL REGISTRATION: This study was registered at the German clinical trials register (DRKS-ID: DRKS00013285).

Outcome after liver resection for primary and recurrent intrahepatic cholangiocarcinoma.

Background: Liver resection is the only curative therapeutic option for intrahepatic cholangiocarcinoma (ICC), but the approach to recurrent ICC is controversial. This study analysed the outcome of liver resection in patients with recurrent ICC. Methods: Demographic, radiological, clinical, operative, surgical pathological and follow-up data for all patients with a final surgical pathological diagnosis of ICC treated in a tertiary referral centre between 2001 and 2015 were collected retrospectively and analysed. Results: A total of 190 patients had liver resection for primary ICC. The 1-, 3- and 5-year overall survival (OS) rates were 74·8, 56·6 and 37·9 per cent respectively. Independent determinants of OS were age 65 years or above (hazard ratio (HR) 2·18, 95 per cent c.i. 1·18 to 4·0; P = 0·012), median tumour diameter 5 cm or greater (HR 2·87, 1·37 to 6·00; P = 0·005), preoperative biliary drainage (HR 2·65, 1·13 to 6·20; P = 0·025) and local R1-2 status (HR 1·90, 1·02 to 3·53; P = 0·043). Recurrence was documented in 87 patients (45·8 per cent). The mean(s.d.) survival time after recurrence was 16(17) months. Independent determinants of recurrence were median tumour diameter 5 cm or more (HR 1·71, 1·09 to 2·68; P = 0·020), high-grade (G3-4) tumour (HR 1·63, 1·04 to 2·55; P = 0·034) and local R1 status (HR 1·70, 1·09 to 2·65; P = 0·020). Repeat resection with curative intent was performed in 25 patients for recurrent ICC, achieving a mean survival of 25 (95 per cent c.i. 16 to 34) months after the diagnosis of recurrence. Patients deemed to have unresectable disease after recurrence received chemotherapy or chemoradiotherapy alone, and had significantly poorer survival. Conclusion: Patients with recurrent ICC may benefit from repeat surgical resection.

Antecedentes: La resección hepática es la única opción terapéutica curativa para el colangiocarcinoma intrahepático (intrahepatic colangiocarcinoma, iCCA), pero el enfoque terapéutico de la recidiva del iCCA es controvertido. En este estudio se analizaron los resultados de la resección hepática en pacientes con recidiva de un iCCA. Métodos: Se recopilaron de forma retrospectiva y se analizaron los datos demográficos, radiológicos, clínicos, quirúrgicos, de anatomía patológica y de seguimiento de todos los pacientes con diagnóstico anatomopatológico definitivo de iCCA en un centro de referencia terciario entre 2001 y 2015. Resultados: En total, 190 pacientes se sometieron a resección hepática por iCCA primario. La supervivencia global (overall survival, OS) a 1, 3 y 5 años fue del 75%, 57% y 38%, respectivamente. La edad de ≥ 65 años (cociente de riesgos instantáneos, hazard ratio, HR 2,2, i.c. del 95% 1,2­4,0, P = 0,012), la mediana del diámetro del tumor ≥ 5 cm (HR 2,9, i.c. del 95% 1,4­6,0, P = 0,005), el drenaje biliar preoperatorio (HR 2,6, i.c. del 95% 1,3­6,2, P = 0.025) y el estado local R1/2 (HR 1,9, i.c. del 95% 1,0­3,5, P = 0,043) fueron factores pronósticos independientes de la OS. La recidiva se documentó en 87 (45,8%) pacientes. El tiempo medio de supervivencia después de la recidiva fue de 16 ± 2 meses. Los factores pronósticos independientes de recidiva fueron la mediana del diámetro del tumor ≥ 5 cm (HR 1,7, i.c. del 95% 1,1­2,7, P = 0,020), el tumor de alto grado (G3­G4) (HR 1,6, i.c. del 95% 1,0­2,5, P = 0,034) y el estado local R1 (HR 1,7, i.c. del 95% 1,1­2,6, P = 0,020). La resección repetida con intención curativa se realizó en 25 pacientes con iCCA recidivado, con una supervivencia media de 25 meses (i.c. del 95% 16­34 meses) tras el diagnóstico de recidiva. Los pacientes que se consideraron no resecables después de la recidiva se sometieron a quimioterapia o quimiorradioterapia y presentaron una supervivencia significativamente peor. Conclusión: Los pacientes con recidiva de un iCCA pueden beneficiarse de la resección quirúrgica repetida.

[Tracheostomy techniques]. / Tracheotomietechniken.

Due to the comprehensive establishment of modern techniques, tracheostomy has become a routine procedure in intensive care units (ICU). The negative effects of prolonged translaryngeal intubation on the laryngeal and tracheal mucosa up to tracheal stenosis can be reduced by tracheostomy. Furthermore, long-term ventilation is facilitated; however, there is no clear evidence on the optimal timing of tracheostomy in critically ill patients. The specific indications and contraindications of surgical as well as percutaneous tracheostomy must be strictly observed for a safe and successful intervention. Exchanging the tracheostomy tube may lead to potentially dangerous situations especially after percutaneous tracheostomy. A standardized and structured approach is therefore recommended.

Phase I and II metabolism and MRP2-mediated export of bosentan in a MDCKII-OATP1B1-CYP3A4-UGT1A1-MRP2 quadruple-transfected cell line.

BACKGROUND AND PURPOSE: Hepatic uptake (e.g. by OATP1B1), phase I and II metabolism (e.g. by CYP3A4, UGT1A1) and subsequent biliary excretion (e.g. by MRP2) are key determinants for the pharmacokinetics of numerous drugs. However, stably transfected cell models for the simultaneous investigation of transport and phase I and II metabolism of drugs are lacking. EXPERIMENTAL APPROACH: A newly established quadruple-transfected MDCKII-OATP1B1-CYP3A4-UGT1A1-MRP2 cell line was used to investigate metabolism and transcellular transport of the endothelin receptor antagonist bosentan. KEY RESULTS: Intracellular accumulation of bosentan equivalents (i.e. parent compound and metabolites) was significantly lower in all cell lines expressing MRP2 compared to cell lines lacking this transporter (P < 0.001). Accordingly, considerably higher amounts of bosentan equivalents were detectable in the apical compartments of cell lines with MRP2 expression (P < 0.001). HPLC and LC-MS measurements revealed that mainly unchanged bosentan accumulated in intracellular and apical compartments. Furthermore, the phase I metabolites Ro 48-5033 and Ro 47-8634 were detected intracellularly in cell lines expressing CYP3A4. Additionally, a direct glucuronide of bosentan could be identified intracellularly in cell lines expressing UGT1A1 and in the apical compartments of cell lines expressing UGT1A1 and MRP2. CONCLUSIONS AND IMPLICATIONS: These in vitro data indicate that bosentan is a substrate of UGT1A1. Moreover, the efflux transporter MRP2 mediates export of bosentan and most likely also of bosentan glucuronide in the cell system. Taken together, cell lines simultaneously expressing transport proteins and metabolizing enzymes represent additional useful tools for the investigation of the interplay of transport and metabolism of drugs.

[The new patient rights act : the significance for surgeons]. / Zum neuen Patientenrechtegesetz : Bedeutung für den Chirurgen.

The committee draft for the new patient rights act was approved by the Federal Cabinet on 23 May 2012. Both the demands of the patient representative of the Federal government and some of the demands from the cornerstone paper of the State commission were taken into consideration.The draft of the new act contains comprehensive amendments to the Civil Code with the subtitle"Treatment contract in accordance with §630" and encompasses §§630a-h. The valid legal situation is therefore to all intents and purposes now codified.

[Valid liability law in surgery. Principles of legal requirements and clinical benchmarks exemplified by visceral surgery]. / Über das geltende Haftungsrecht in der Chirurgie. Grundsätzliche juristische Vorgaben und klinische Bezugspunkte am Beispiel der Viszeralchirurgie.

The spectacular increase in liability processes in the field of surgery and in particular in visceral surgery, necessitates an objectification of the conflict between surgical medical professionals and medico-legal institutions, firms of solicitors and courts. Out of court settlements assisted by expert opinion commissions of the Medical Council can avoid many legal conflicts. For improvement of the legal standpoint of a defendant medical professional an unambiguous, extensive and detailed documentation of medical examination findings, the indications for the planned operative intervention, extensive and detailed documentation on disclosure and informed consent of the patient for the planned operative intervention, an extensive, detailed careful and responsibly guided report of the operation as well as a systematic, orderly well-planned postoperative complication management are necessary to counter the accusation of an organizational failure of medical professionals and the accused hospital. The mutual building of confidence between surgical medical professionals and legal institutions is safeguarded by a comprehensive documentation and an unambiguous description and formulation of the medical discharge report on termination of inpatient treatment.

Identification of drugs and drug metabolites as substrates of multidrug resistance protein 2 (MRP2) using triple-transfected MDCK-OATP1B1-UGT1A1-MRP2 cells.

BACKGROUND AND PURPOSE: The coordinate activity of hepatic uptake transporters [e.g. organic anion transporting polypeptide 1B1 (OATP1B1)], drug-metabolizing enzymes [e.g. UDP-glucuronosyltransferase 1A1 (UGT1A1)] and efflux pumps (e.g. MRP2) is a crucial determinant of drug disposition. However, limited data are available on transport of drugs (e.g. ezetimibe, etoposide) and their glucuronidated metabolites by human MRP2 in intact cell systems. EXPERIMENTAL APPROACH: Using monolayers of newly established triple-transfected MDCK-OATP1B1-UGT1A1-MRP2 cells as well as MDCK control cells, single- (OATP1B1) and double-transfected (OATP1B1-UGT1A1, OATP1B1-MRP2) MDCK cells, we therefore studied intracellular concentrations and transcellular transport after administration of ezetimibe or etoposide to the basal compartment. KEY RESULTS: Intracellular accumulation of ezetimibe was significantly lower in MDCK-OATP1B1-UGT1A1-MRP2 triple-transfected cells compared with all other cell lines. Considerably higher amounts of ezetimibe glucuronide were found in the apical compartment of MDCK-OATP1B1-UGT1A1-MRP2 monolayers compared with all other cell lines. Using HEK cells, etoposide was identified as a substrate of OATP1B1. Intracellular concentrations of etoposide equivalents (i.e. parent compound plus metabolites) were affected only to a minor extent by the absence or presence of OATP1B1/UGT1A1/MRP2. In contrast, apical accumulation of etoposide equivalents was significantly higher in monolayers of both cell lines expressing MRP2 (MDCK-OATP1B1-MRP2, MDCK-OATP1B1-UGT1A1-MRP2) compared with the single-transfected (OATP1B1) and the control cell line. CONCLUSIONS AND IMPLICATIONS: Ezetimibe glucuronide is a substrate of human MRP2. Moreover, etoposide and possibly also its glucuronide are substrates of MRP2. These data demonstrate the functional interplay between transporter-mediated uptake, phase II metabolism and export by hepatic proteins involved in drug disposition.

[Long-term consequences of postoperative delirium]. / Langzeitfolgen eines postoperativen Delirs.

A patient reported anxiety and sleeping problems 9 months after reconstruction of the anterior floor of the mouth following tumor surgery. These symptoms had been initiated by a postoperative delirium with hallucinations, which had not been detected during its occurrence. One session of psychotherapy 9 months later reduced the symptoms. Patients in intensive care units should be asked and informed about delirium symptoms. This might prevent long-term psychological distress.

First outbreak of Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae in Germany.

We report the first outbreak of Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae in Germany. The presence of KPC was confirmed by polymerase chain reaction (PCR). The KPC-encoding plasmid was analysed by transconjugation experiments, DNA sequencing, Southern blotting and isoelectric focussing. Typing was performed by pulsed-field gel electrophoresis (PFGE). An ertapenem-resistant K. pneumoniae with low minimum inhibitory concentrations (MIC) to other cabapenems (tested by the Vitek system) was isolated from the index patient in January 2008. A KPC-2 was identified after K. pneumoniae with identical susceptibility patterns had been isolated from two more patients. Despite the introduction of infection control measures, transmission occurred in five additional patients and three of the patients died from infections. The source of the outbreak strain remained unclear; however, the Tn4401-containing bla (KPC-2) gene was similar to previously described isolates from Greece. Five months after the end of the outbreak, a KPC-K. pneumoniae was isolated from a patient who had been treated in Greece previously. Retrospectively, this patient was treated in November 2007 on the same unit as the index case. Typing revealed that all patients were colonised by the same strain. KPC-K. pneumoniae has been introduced to Germany possibly from Greece and transmission to other institutions is likely.

Incorporation of the bone marker carboxy-terminal telopeptide of type-1 collagen improves prognostic information of the International Staging System in newly diagnosed symptomatic multiple myeloma.

Several prognostic markers, including parameters of tumor burden and cytogenetics, were adopted to identify high-risk patients in multiple myeloma (MM). Recently, the International Staging System (ISS), including beta2-microglobulin (beta2M) and albumin, was introduced for patients with symptomatic MM. As bone disease is a hallmark of MM, we investigated the prognostic impact of the bone resorption marker carboxy-terminal telopeptide of type-1 collagen (ICTP) in combination with ISS, beta2M, albumin, deletion of chromosome 13 and high-dose therapy (HDT) in 100 patients with newly diagnosed symptomatic MM. beta2M alone, albumin alone, ISS, HDT, del(13q14) and ICTP were significant prognostic factors for overall survival (OS). In a multivariate analysis, ICTP was the most powerful prognostic factor (log-rank P<0.001, hazard ratio: ninefold increase). ICTP clearly separated two subgroups with a good and a worse prognosis within each of the three ISS stages (ISS I: P=0.027, ISS II: P=0.022, ISS III: P=0.013). Incorporation of ICTP in a combined ICTP-ISS score significantly (P<0.001) separated four risk groups with a 5-year OS rate of 95, 64, 46 and 22%, [corrected] respectively. These data demonstrate for the first time that the inclusion of the collagen-I degradation product ICTP, as a biomarker of bone resorption, adds to the prognostic value of ISS.

Bortezomib inhibits human osteoclastogenesis.

In multiple myeloma, the overexpression of receptor activator of nuclear factor kappa B (NF-kappaB) ligand (RANKL) leads to the induction of NF-kappaB and activator protein-1 (AP-1)-related osteoclast activation and enhanced bone resorption. The purpose of this study was to examine the molecular and functional effects of proteasome inhibition in RANKL-induced osteoclastogenesis. Furthermore, we aimed to compare the outcome of proteasome versus selective NF-kappaB inhibition using bortezomib (PS-341) and I-kappaB kinase inhibitor PS-1145. Primary human osteoclasts were derived from CD14+ precursors in presence of RANKL and macrophage colony-stimulating factor (M-CSF). Both bortezomib and PS-1145 inhibited osteoclast differentiation in a dose- and time-dependent manner and furthermore, the bone resorption activity of osteoclasts. The mechanisms of action involved in early osteoclast differentiation were found to be related to the inhibition of p38 mitogen-activated protein kinase pathways, whereas the later phase of differentiation and activation occurred due to inhibition of p38, AP-1 and NF-kappaB activation. The AP-1 blockade contributed to significant reduction of osteoclastic vascular endothelial growth factor production. In conclusion, our data demonstrate that proteasomal inhibition should be considered as a novel therapeutic option of cancer-induced lytic bone disease.

[Relevance of surgical outpatient clinics in academic university centers to health care in Germany]. / Stellenwert einer allgemeinen chirurgischen Hochschulambulanz für die medizinische Patientenversorgung Eine ergänzende Erhebung zur "Deutschen Hochschulambulanzenstudie".

During the observation period between 2001 and 2003, all outpatient surgical therapy, including degrees of urgency, surgical care volume, regional provenance of patients, diagnoses, and referral channels were prospectively analysed at the Surgical Department of the University of Heidelberg, Germany. The data gathered do not merely describe the volume and characteristics of care encountered at this academic surgical institution but also provide further insight into the variability of resource utilisation and associated patient flow. Additionally, a retrospective evaluation using structured interviews and questionnaires was performed to differentiate and quantify patient care, teaching, and research activities. This study illustrates the high relevance of academic outpatient institutions to regional provision of general surgical care in Germany. There is a clear dominance of medical support functions, while research and teaching activities are of only minor relevance and realised particularly in subspecialty clinics. These data should give important stimuli for the future planning of health care in Germany. Outpatient clinics for general surgery appear to be an excellent basis for regional models of integrated health care delivery in the future.

[Intracorneal depot steroids for the treatment of corneal rejection after keratoplasty]. / Aplicación de corticosteroides intracorneanos de depósito en el tratamiento de rechazo de queratoplastia.

PURPOSE: To introduce a new type of therapy for corneal rejection after keratoplasty with the microinjection of intrastromal depot cortisone in single or multiple doses. METHODS: Thirty-three consecutive eyes with corneal graft rejection were diagnosed and treated by one of the authors (EA) between January 1998 and November 2000. RESULTS: Of the 33 eyes, 26 were submitted to Penetrating Keratoplasty (PK), five to lamellar, and two to homoplastic keratoplasty. The most common rejection type was epithelial in 20 eyes, 11 eyes showed mixed rejection types and two eyes, endothelial. In 18 of the cases (54.54%) treatment consisted solely of intraestromal injection; in the other 15 cases some other medications were added mostly because of patient anxiety. The vast majority of the cases (81%) improved clinically within a few days after the injection. Fifty-four percent of the cases required a number of doses ranging from one to five; the rest of the cases had a greater number of sessions. Thirty-one cases have been followed up for a period longer than six months without showing increase in intraocular pressure or development of steroid lens opacities. CONCLUSION: Intrastromal depot cortisone injection is a new alternative for the treatment of corneal graft rejections after keratoplasty.

Aplicación de corticosteroides intracorneanos de depósito en el tratamiento de rechazo de queratoplastia / Intracorneal depot steroids for the treatment of corneal rejection after keratoplasty

Objetivo: Presentación de una nueva forma de terapia ocular al tratamiento de rechazo de queratoplastia mediante microinyecciones intracorneanas. Material y métodos: Analizamos 33 pacientes manejados por uno de los autores (EAA), desde enero 1998 a diciembre de 2000.Resultados: El tipo de cirugía más común fue queratoplastia penetrante (n=26), seguida de queratoplastia lamellar (n=5) y homoplastia (n=2). El tipo de rechazo más común fue epitelial (n=20); de rechazo mixto (n=11) y dos casos de endotelial puro. En 18 de los 33 casos (54,54 por ciento) no usamos ningún tratamiento tópico asociado en el resto se adicionó algún tipo de medicamento inducido principalmente por la ansiedad de la paciente. La gran mayoría de los pacientes (81 por ciento) presentó mejoría clínica pocos días despues de la inyección. Se requirieron de una a cinco dosis en 54 por ciento de los casos, en el resto se aplicaron más de cinco sesiones. Los pacientes seguidos por un tiempo mayor de 6 meses (n=31) no han presentado catarata, glaucoma u otras complicaciones alusivas al corticoide. Conclusiones: La inyección intracorneal de corticosteroides reemplaza o potencializa el tratamiento de rechazo en queratoplastia. (AU)

[Structural development of ambulatory surgical care in the United States of America. What can we learn or apply?]. / Strukturelle Entwicklung der ambulanten Chirurgie in den USA Was können wir lernen oder übernehmen?

Expansion of ambulatory surgical care is a major focus in United States health politics. In 1996 a total of 31.5 million ambulatory operations were performed, currently accounting for 45% of yearly procedures. Operations in ophthalmology and gastroenterology are predominant. Ambulatory surgery is organized in different forms: "office-based surgery," "hospital outpatient departments," and "ambulatory surgery centers" (ASC). The numbers of ASCs are rapidly increasing. The current proportion of ASCs is 16% of all operations. The type of ambulatory surgery is primarily defined by payors. Medicare standards are the benchmark for private organizations. Recovery care centers now offer postoperative care beyond the former 23-h threshold. This may lead to a further expanded ASC access. Revenues for ambulatory surgery were so far mostly based on fees for service. The implementation of an outpatient prospective payment system ("OPPS") is planned by Medicare, using fixed package prices within a newly defined ambulatory payment classification ("APC"). The dimension of structural changes could be enormous and possibly be compared with the implementation of DRGs in 1983.

[Documentation of surgical performance--does more really help more? Comparison of the effects of maximum and limited documentation depth of clinical patient data on theoretical revenue volume of a surgical clinic after introduction of the DRG-based reimbursement system]. / Chirurgische Leistungsdokumentation--Hilft viel wirklich viel? Vergleich der Auswirkung von maximaler und geringer Dokumentationstiefe klinischer Patientendaten auf das theoretische Ertragsvolumen einer chirurgischen Klinik nach Einführung des DRG-basierten Entgeltsystems.

INTRODUCTION: The forthcoming introduction of a DRG-based account system in Germany aims at higher transparency and economic efficiency, particularly in the sector of in-patient health care. The availability of documentation of the highest quality, taking into account all potentially relevant diagnoses, appears to be the best method for achieving maximum revenue in individual surgical units. The aim of the study was to determine the relevance of various degrees of documentation depth on calculated DRG-based revenue. Furthermore, we evaluated whether improvements in the quality of documentation can be realized in current hospital organization. METHODS: In a prospective study, clinical data from 402 in-patients were collected and revenues were calculated based on the Australian-Refined DRG system. Various qualities of documentation were defined. In order to find the medical sectors most sensitive to "under-documentation", homogenous cases were classified into 23 treating groups, according to diagnosis. RESULTS: In 267 cases, maximum revenue was determined only by one main diagnosis, while better results could be achieved in 137 cases (34%) by extended documentation quality. Half of this gain could only be achieved by an independent medical documentation specialist. An upper limit of documentation intensity (number of diagnoses) could be defined. Maximum gain did not require maximum number of diagnoses. CONCLUSIONS: Documentation depth has an important influence on the calculated revenue of surgical therapy based on AR-DRG system. The quality and depth of the documentation is not, in itself, sufficient. In order to be really effective, it requires the highest degree of professionalism from hospital staff.

[Operational costs and control of performance in surgical clinics between marketing and planning economics. Risk or perhaps quadrature of the circle]. / Betriebswirtschaftliche Kosten- und Leistungsteuerung in chirurgischen Kliniken zwischen Markt- und Planwirtschaft. Riskanter Spagat oder gar Quadratur des Kreises.

Surgical hospitals can be seen as operational or even industrial production systems. Doctors have a major impact on both medical performance and costs. For active participation in the management process, knowledge of industrial controlling mechanisms is required. German hospitals currently receive no procedure-related financial revenues, such as prices or tariffs for defined medical treatment activities. Maximum clinical revenues are, furthermore, limited by principles of planned economy and can be increased only slightly by greater medical performance. Costs are the only target that can be autonomously influenced by the management. Operative controlling in hospitals aims at horizontal and vertical coordination of subunits and decentralization of process regulations. Hospital medical performance is not clearly defined, its quantitative measurement very problematic. Process-orientated clinical activities are not taken into account. A high percentage of hospital costs are fixed and can be influenced only by major structural interventions in the long term. Variable costs are primarily dependent on the quantity of clinical activities, but also heavily influenced by patient structure (comorbidity and risk profile). The various forms of industrial cost calculations, such as internal budgeting, internal markets or flexible plan-cost balancing, cannot be directly applied in hospital management. Based on these analyses, current operational concepts and strategic trends are listed to describe cost-management options in hospitals with focus on the German health reforms.

[GSG (Structured Health Regulation)-conforming documentation of surgical interventions in a university clinic--3 years clinical experiences 1994-1996]. / GSG-konforme Dokumentation operativer Eingriffe an einer Universitätsklinik--3 Jahre klinische Erfahrung 1994-1996.

The cost increase in the public health sector is steadily mounting and hence politicians are forced to redefine the economic conditions for regulations. As a new quality in the area of inpatient hospital care the new German law of structural health care (GSG), valid as of January 1, 1993 replaces the principle of covering full costs. The GSG law required in our hospital an adjustment of existing EDP structures with integrated automatic remuneration estimate and the installation of a medical structure of the organisation for complete and correct documentation. Weakpoints of the prescribed obligatory ICPM codes and inadequate legal regulations result in a lack of separation or wrong integration of the lump sum payment in individual cases (FP) and special compensation (SE). The summary analysis of the compensation system with a subsequent medical control system showed a primarily inaccurate classification by 12%. There is as yet no proof for the usefulness of a lump sum payment system resulting in a selection of risks.

[Analysis of the acceptance of the internet presentation of the 115th Congress of the German Society of Surgery]. / Akzeptanzanalyse der Inernetpräsentation des 115. Kongresses der Deutschen Gesellschaft für Chirurgie.

The World Wide Web presentation of the 115th Annual Meeting of the German Society of Surgery was examined with regard to the frequency of hits per day and the use made of the online offers. The high frequency of the hits clearly shows the high acceptance of this medium. The temporal distribution of the hits imply that the group that was aimed at, namely "surgeons", have indeed been reached.
